BACKGROUND

The invention in general relates to tools to manage job scheduling and execution on a grid infrastructure. In particular, the invention relates to a method and system for automatic execution of scripts on remote agent-less client machines.

Grid computing is defined as a mechanism to overcome heterogeneity of computing elements, operating systems and policy decisions and environment. The long-term vision of the enterprise grid computing community is non-dedicated, seamless interoperability of disparate systems that may be part of the same organization or different organizations. Grid computing is looked upon by many experts as a technology that can change the world, like the internet. But from the user's point of view, grid is nothing but a computer with a huge amount of computing resource. Many applications in domains like Life sciences, Energy, Finance etc. require huge resources to run compute-intensive jobs through a business workflow. Therefore, there is a need for business level workflow definitions integrated with run book automation tool to interact with the underlying heterogeneous grid infrastructure and execute scripts or jobs comprising the workflow across the infrastructure.

However, most of the run book automation tool required agent to be installed on the target machines or plug-in to be integrated with the tool for establishing connection between the central server and target machines and to execute the jobs present in the workflows in the target machine.

There has to be a system and a method to generate workflow definitions and execute scripts on target machines without plug-in integration with the system and agent installation on the target machines.

Thus, there is a need for a system and a method that automatically generates workflows and executes scripts on target remote agent-less client machines without requiring plug-in integration with the system.

Of course, many modifications and adaptations will be apparent to those skilled in the relevant arts in view of the following description in view of the accompanying drawings and the appended claims. While the system and method described herein are provided with a certain degree of specificity, the present technique may be implemented with either greater or lesser specificity, depending on the needs of the user. Further, some of the features of the present technique may be used to get an advantage without the corresponding use of other features described in the following paragraphs. As such, the present description should be considered as merely illustrative of the principles of the present technique and not in limitation thereof, since the present technique is defined solely by the claims.

FIG. 1 is a block diagram of a system 100 illustrating interaction between one or more users 102 and various components of system 100 configured to automatically generate one or more workflows and execute one or more scripts on one or more remote agent-less machines, in accordance with an embodiment of the present invention. The system 100 is a web based run book automation tool configured to execute scripts and executables across multiple platforms via a secured communication protocol. There are many types of secured communication protocols and the selection of the secured communication protocol is based on the operating system in which the system 100 is deployed. For example the communication protocol could be Secure Shell (SSH) Protocol, if the system 100 is deployed in UNIX operating system, or psexec protocol, if the system 100 is deployed in Windows operating system. The system 100 as depicted in FIG. 1 includes the following components: an authenticator 104, a workflow generator 108, a script runner 114, an audit log generator 120 and a report generator 122.

Authenticator 104 authenticates one or more users 102 logging into the system 100 and provides access privileges to one or more valid users based on their role. The access privileges for one or more users based on their role restrict unprivileged users in accessing and initiating critical activities in the system 100.

Workflow generator 108 generates one or more optimized decision support workflows that can be carried out on a grid infrastructure based on one or more input scripts 106 obtained from one or more users. Workflow generator 108 includes the following modules: Generate workflow module 110 and Map workflow module 112.

Generate workflow module 110 receives one or more input scripts 106 from one or more users. Each input script 106 in the generate workflow module 110 consists of at least one project requirement and at least one system configuration information as input parameters, wherein said at least one project requirement could be one of a project code or a remote agent-less client machine detail, and said at least one system configuration comprises operating system information of the remote agent-less client machine. The project code comprises a unique code to identify project group and the remote agent-less client machine detail comprises a machine IP address.

The generate workflow module 110 resolves dependency of one or more input scripts 106 based on the input parameters and generates optimized decision support workflow which provides dynamic support while executing a workflow.

Map workflow module 112 retrieves one or more generated optimized decision support workflow and maps it to one or more remote agent-less client machine based on the input parameters.

Script runner 114 retrieves one or more optimized decision support workflow mapped with one or more remote agent-less client machines from the map workflow module 112. Script runner 114 consists of execute scripts module 116.

Execute scripts module 116 executes one or more input scripts 106 on mapped one or more remote agent-less client machines based on the retrieved optimized decision support workflow. Results of script execution 118 are recorded by the execute scripts module 116 and notified to one or more users 102 and audit log generator 120. The results of script execution 118 could be success for successful execution of scripts on the respective remote agent-less client machine or failure for failed execution of scripts on the respective remote agent-less client machine. Script runner 114 does not require any plug-in integration or any agent installation on target client machine to track the results of script execution 118 and communicating it to one or more users 102.

Audit log generator 120 retrieves the results of script execution 118 from the execute scripts module 116 of the script runner 114 and records an audit log comprising a transaction information. The transaction information comprises user information, timestamp and status of the transaction from workflow generation to execution of scripts, wherein said user information comprises information regarding one or more users responsible for initiating a workflow generation and script execution, and said status of the transaction comprises success or failure results of script execution 118. Audit log generator further comprises a report generator 122.

Report generator 122 retrieves one or more audit logs recorded by the audit log generator 120 and generates one or more reports based on the selection by one or more users 102 on each reporting period, wherein the reporting period is a group consisting of a day, a week, a month, a quarter and a year.

FIG. 2 is a flowchart describing a method for automatically generating one or more workflows and executing one or more scripts on one or more target remote agent-less client machines, in accordance with an embodiment of the present invention.

The process of automatically generating one or more workflows and executing one or more scripts on one or more target remote agent-less client machines, involves the following steps:

At step 202, receive one or more input scripts to be executed on one or more target remote agent-less client machines along with input parameters from one or more users. Each input parameter consists of at least one project requirement and at least one system configuration information, wherein said at least one project requirement could be one of a project code or a remote agent-less client machine detail and said at least one system configuration comprises operating system information of the remote agent-less client machine. The project code comprises a unique code to identify project group and the remote agent-less client machine detail comprises a machine IP address.

At step 204, generate one or more optimized decision support workflow based on one or more input scripts and one or more input parameters wherein the one or more optimized decision support workflow resolves dependency of one or more input scripts to be executed on one or more target remote agent-less client machines and provides dynamic support during the execution of one or more scripts on the target remote agent-less client machines.

At step 206, map the one or more optimized decision support workflow generated in step 204, with the target remote agent-less client machines.

At step 208, retrieve one or more optimized decision support workflow that is mapped with the target remote agent-less client machines and execute one or more input scripts in the target remote agent-less client machines.
